Amino acids and some other organic compounds, perhaps nucleic acids.
Miller and Urey observed the abiotic synthesis of amino acids, the building blocks of proteins, in their laboratory simulations of the early Earth. Additionally, they also observed the formation of other organic molecules like sugars and nucleotides, which are essential for life.
Oparin's hypothesis proposed that Earth's early atmosphere could have supported the formation of organic molecules, providing the foundational idea for Miller and Urey's experiment. Miller and Urey's experiment aimed to simulate early Earth conditions and demonstrated that organic molecules, including amino acids, could indeed be produced in a laboratory setting, supporting Oparin's hypothesis.
The Miller-Urey experiment is not definitive proof of the origins of life. It provided important insights into how simple organic molecules could have formed on early Earth, but it does not fully explain the complex processes involved in the origin of life.
The Miller-Urey experiments provided support for the hypothesis that the complex molecules necessary for life could arise from simpler compounds present on early Earth. This is important for understanding how life could have potentially originated through chemical processes on the planet.
Stanley Miller and Harold Urey were two scientists who send electrical currents through gases that were believed to be Earth's early atmosphere (water vapor, ammonia, hydrogen, and methane). When the gases cooled, they thickened to make a salt water-like liquid that had things in it like amino acid, what is found in present-day cells.

Stanley Miller and Harold Urey
The Miller-Urey experiment demonstrated that under conditions simulating early Earth's atmosphere, organic molecules essential for life, like amino acids, could be formed from inorganic compounds through abiotic synthesis. This supported the hypothesis that the building blocks for life could have arisen from simple chemical reactions on the primitive Earth.

I think you have Miller and Urey confused with someone else.
The purpose of the Miller-Urey experiment was to simulate early Earth conditions and investigate the origin of life by creating amino acids, the building blocks of proteins, through the use of electricity to mimic lightning in a reducing atmosphere. This experiment aimed to provide evidence for the abiotic synthesis of organic compounds, supporting the hypothesis that the essential building blocks of life could have formed on early Earth.
The sparks used as the energy source in the Miller-Urey experiment represented lightning strikes in the early Earth's atmosphere. This was meant to simulate the energy provided by natural electrical discharges, which were essential to the synthesis of organic compounds from inorganic molecules in the primordial environment.
Miller and Urey's experiments attempted to demonstrate the chemical origins of life. They first conducted the experiment in the year 1953.
amino acids, which are the building blocks of proteins, by simulating the conditions that existed on early Earth. This experiment provided evidence to support the idea that the abiotic synthesis of organic molecules, such as amino acids, could have contributed to the origin of life on Earth.
Oparin's hypothesis proposed that Earth's early atmosphere could have supported the formation of organic molecules, providing the foundational idea for Miller and Urey's experiment. Miller and Urey's experiment aimed to simulate early Earth conditions and demonstrated that organic molecules, including amino acids, could indeed be produced in a laboratory setting, supporting Oparin's hypothesis.
The Miller-Urey experiment showed that simple organic molecules, including amino acids, could be formed from inorganic precursors under conditions simulating early Earth. Over time, subsequent research and alternative experiments have further supported the idea that the prebiotic synthesis of organic compounds is plausible, contributing to our understanding of the origins of life on Earth.
